Spi MS170111044 Gage Block Base Block 4 Inch

Product Description

The SPI MS170111044 is a gage block base block designed to support and stabilize rectangular gage blocks during precision measurement tasks. With an overall length of 4 inches and a height accuracy of plus or minus 0.00002 inches, this base block provides a repeatable, stable foundation for high-tolerance measurement setups. It is used in metrology labs, calibration environments, and quality control stations where dimensional accuracy is critical. Machinists, metrologists, and QC technicians working with gage block assemblies rely on base blocks like this to ensure consistent block orientation and reduce measurement error.

This base block is suited for use in precision measurement applications across manufacturing, toolroom, and inspection environments. It is specifically designed for use with rectangular gage blocks and is sold as a single piece. Typical applications include surface plate work, height measurement setups, and gage block wringing assemblies where a stable base is required to hold blocks in a fixed, repeatable position.

Key Features

Installation Notes

Installation and use should be performed by trained metrologists, machinists, or quality control technicians familiar with gage block handling procedures. Clean all mating surfaces thoroughly before assembling to prevent measurement error caused by contamination or debris. Avoid dropping or striking the base block, as impact damage can compromise accuracy. Store in a protective case when not in use to maintain surface integrity.
